摘　　要：目的测定外卖餐具中16种合成酚类抗氧化剂(synthetic phenolic antioxidants,SPAs)的含量,分析外卖餐具中这类污染物的迁移行为。方法本研究通过液相色谱-串联三重四极杆质谱法和气相色谱-串联三重四极杆质谱法,测定了6大类不同品牌外卖餐具中16种SPAs的含量。分别以纯净水、4%醋酸(V/V)、10%乙醇水溶液(V/V)、50%乙醇水溶液(V/V)和95%乙醇水溶液(V/V)为食品模拟物,开展不同品牌外卖餐具中主要SPAs的迁移实验。结果外卖餐具中均可以检出1种以上SPAs,其中2,6-二叔丁基对甲酚及其代谢物的含量和检出率最高,2,4-二叔丁基苯酚和新兴化合物2,2’-亚甲基双-(4-甲基-6-叔丁基苯酚)次之,然而2,4-二叔丁基苯酚是外卖餐具最主要的迁移物。结论外卖餐具中合成酚类抗氧化剂广泛存在。2,4-二叔丁基苯酚在外卖餐具中大量迁出,其健康危害需要引起足够关注。Objective To determine the content of 16 kinds of synthetic phenolic antioxidants(SPAs)in takeaway tableware,and analyze the migration behavior of such pollutants in takeaway tableware.Methods In this study,the content of 16 kinds of SPAs in 6 categories of take-away tableware with different brands were determined by liquid chromatography-tandem triple-quadrupole mass spectrometry and gas chromatography-tandem triple quadrupole mass spectrometry.Pure water,4%acetic acid(V/V),10%ethanol aqueous solution(V/V),50%ethanol aqueous solution(V/V)and 95%ethanol aqueous solution(V/V)were used as food simulants to develop take-away tableware with different brands.Results More than one SPAs could be detected in take-away tableware,among which the content and detection rate of 2,6-di-tert-butyl-4-methylphenol and its metabolites were the highest,followed by 2,4-di-tert-butyl-phenol and emerging compound 2,2’-methylenebis-(4-methyl-6-tert-butylphenol),but 2,4-di-tert-butyl-phenol was the main migration of take-away tableware.Conclusion SPAs are widely found in take-away tableware.2,4-di-tert-butyl-phenol moves out in large quantities in take-away tableware,and its health hazards need to be paid enough attention.
